[ELDK] Unable to boot Linux Kernel 2.6.24 into MPC5200 (lite5200b)

[Peter Kuennemann]

Hi Folks, I am seeking for some advise to get my lite5200b board up and 
running with a linux kernel.
I installed the most recent eldk version from iso image ppc-2008-04-01, 
run a kernel config with

$ make  52xx/lite5200b_defconfig 
$ make uImage
(Environment has been set to: CROSS_COMPILE="ppc_6xx-" and ARCH="powerpc")

I followed the eldk documentation and advices and got compile and link run
without any problem but the image does not boot at all with uboot.

An existing 2.4 Kernel does boot (I do not have a change to rebuild it), 
also the binary image that is delivered by  Freescale in their board 
support package do boot, all with almost identical uboot arguments.

I have played with several bootargs settings, used console=ttyS0 and 
console=ttyPSC0. Boot always stops after:

I have checked the net for advise and tried a lot but nothing helped. I
assume
That there must be something very generic wrong.

Any advises are higly welcome.
